PENNSYLVANIA, ASSIGNOR OF ONE-HALF T0 A. LINCOLN TAYLOR, 0F HADDON HEIGHTS, NEW JERSEYl WINDOW SASIEI Application filed November The object of the invention is to provide improvements in window sash, and particularly in that class in which each sash unit comprises main and secondary frame members, pivotally connected together so that one may be oscillated with respect to the other.

In the construction of oflice and similar buildings today there is an ever increasing need of a window construction which will permit the panes to be cleaned from the inside, and attempts have been made to solve this problem with varying results, but apparently little or no attention has been paid to the needs in this line of window construction in domestic establishments.

The object of the invention is therefore to provide a principle of construction, which by alteration of minor details of size and arrangement will adapt the same for use by both business buildings and residential structures, so that the regular cleaning force of the former and the housekeeper or maid of the latter can clean the outside of both the upper and lower sash of a window, as we-ll as the f inside thereof, with the utmost ease and con- Venience, and without necessitating that anyone shall have to lean out of or sit or stand upon, the window sill.

1n addition to the foregoing, an object of the invention has been to so construct the main and secondary frames, that each improved sash as a unit operates to positively prevent the passage, either of wind when blowing in any direction whatever, or of rain and sleet when being driven at unusual angles.

With the objects of the invention thus broadly'stated, the invention comprises novel details of construction and operation, which are hereinafter fully brought out in the foilowing description, when read in conjunction with the accompanying drawings, in which Fig. 1 is a front elevation of a window comprising one embodiment of the invention Fig. 2 is a rear view of the same; Figs. 3, 4 and 5 are sections on the lines 3 3, 4 4 and 5 5, respectively, of Fig. 2; Fig. 6 is an elevation of the main sash frame; and Fig. 7 is a correspending view of the secondary sash frame.

Referring to the drawings, it will be as@ sumed that the device is operatively posi- 1, 1929. serial No. 404,000. y

tioned for use in the usual manner.` For this purpose a wall 1 is shown as being provided with a rectangular aperture 2, within which latter is positioned the window frame. This frame is composed of the usual sash guide 3, having a central bead 4 to provide spaced grooves or tracks 5 and 6, in whichsash units are adapted to reciprocate. The laterally opposite limits of these tracks are defined by forward and rearward face members 7 and 8, which extend freely from the guide 3 in spaced relation with each other, to provide boxes 9 for the reception of the usual sash weights (not shown), the opposite or outer sides of said boxes being closed by wall-engaging members 10, and the union or connection between said last-named members and said wall being covered by suitable moulding strips 11.

Each of the sash units for both the upperv and lower portions of the frame is composed as before mentioned o'f amain and a secondary member, shown respectivelyin Figs. 6 and 7. The main sash member comprises, a preferably rectilinear element formed of top, bottom and side pieces, 12, 13 and 14, respectively. .The top piece and the upper, substantially one-half portion of each of the side pieces are i' extended'inwardly by means of an exceedingly deep flange 15, substantially equal in width to the corresponding portions of the top and side pieces 16 and 17 of the secondary sash member shown in Fig. 7, said latter being bridged at'their lower ends by a bottom piece 18, and all co-operating to support the usual glass pane 19.

The lower, substantially one-half portion of the side pieces 14`of said main sash member are cut away at 20, to provide flanges 21 which are connected at their lower ends by the bottom piece 13, of similar thickness. A SaidV cut away regions are thus adapted to receive laterally extending flanges 22, carried by the lower portions of the side pieces 17, while a flange 23 carried bythe bottom piece 18 of Vma Vsaid secondary sash normally lies snugly and dat against the bottom'piece 13 of said main sash, as shown in Figs, 3, 4 and 5, the corresponding top, side and bottom pieces of said main and secondary sashes co-operating to 10@ 25 ings or decorations which may be present.

l after the secondary sash has been reversed for cleaning, replacement of the pane, orV otherwise as may be desired, its weight oper-l ates to ,start its return movement towards normal position, whence Vit-can be manually shifted at will after releasing any suitable form of latch, which in the present instance has been illustrated as comprising a springpressed pin 25 of well-known type, since such avpin when used in the upper of said sash units is out of the path of reciprocation of the lower unit, and when used in the lower unit is out of the way of shades or other hang- Furthermore, by using a hinge ysupport of the type here illustrated it is obvious that, as the secondary sash approaches its reversed position, it correspondingly approaches a condition in which the friction between the adjacent sides of the sash sections becomes a minimum. In the case of certain other sash constructions, in which the a-Xis of oscillation passes thru a transversely central portion thereof, the friction between the sash members beginning with -normal position decreases towards a horizontal position, after which the friction again increases at the same rate, due to the normal lower portion of the secondary sash again entering the space between the sides of the main sash. In the present case, however, this lower secondary sash portion, after being once removed from within the main sash, does not again enter the latter as it approaches its reversed position.

I-Iaving thus described my invention, what I claim and desire to protect by Letters Patent of the United States is y l. A window sash, comprising a closed rectangular main member, the upper portion of vided with a marginal cutaway portion said ange and cutaway portions upon each side of said lirst member terminating insubstantial alignment with' each other, and a second- YYary sash member -pivotally mounted in said member, with its upper portion of substantially the same width and normally lying against said flange, and the lower portion of said secondary member being provided with an integral lange at the sides normally lying in said cutawayportionand at the bottom lying across the corresponding portion of said main member.

In testimony whereof I have aixed my signature. y i
